A new technique developed by scientists at California’s Stanford University has confirmed that the Los Angeles would experience stronger-than-anticipated ground movement should major seismic activity occur to the city’s south.

Georgia Basin May Amplify Ground Shaking From Next Quake In Vancouver
2014-01-21 08:15:38

Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin

NASA JPL Scientist Reflects Last Big Quake In Los Angeles

Geophysicist Andrea Donnellan of NASA's Jet Propulsion Laboratory, Pasadena, Calif., reflects on the Northridge earthquake, what we've learned about earthquakes since then, our state of preparedness for the next "big one" and what lies ahead for earthquake studies at NASA.

Researchers Develop Building 'Belt' For Cheap, Quick Repair Of Earthquake Damage

Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources. There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...
